Description Models 2652 and 2653 are members of Sensoray's 2600 series of smart I/O modules. Model 2652 monitors and controls any combination of up to eight standard solid state relays (SSRs) and the 2653 can handle up to sixteen SSRs. These modules connect to a 2601 communication module, which in turn enables remote Ethernet clients to monitor and control the SSRs. Simple system with up to 16 SSRs The 2652 and 2653 SSR modules communicate with a 2601 communication module through an optically isolated interface, thereby eliminating problematic ground loops and ensuring error-free operation in demanding industrial environments. Two cables connect the 2653/2653 to the 2601: a standard Category-5 UTP patch cable for inter-module communication, and a six-conductor power cable that supplies control power for the SSRs through an integral safety interlock system. The 2600 family is well suited for applications that have high I/O counts. As many as sixteen I/O modules, in any combination of I/O module types, can be connected to a 2601. This enables, for example, up to 256 solid state relays to be controlled from a single Ethernet port. More complex system with up to 256 SSRs Solid-State Relays Sockets are provided for eight (model 2652) or sixteen (model 2653) SSRs. Each relay socket may be populated with any of the supported SSR types, including AC in, AC out, DC in and DC out, or left unpopulated. SSRs are secured to the module with integral hold-down screws. Field Wiring On-board, finger-safe connectors enable direct connections to all field wiring. Two connectors are provided for each SSR, one for the line connection and one for the load. This organization greatly simplifies the field wiring and enables electric loads to be easily connected and disconnected for quick servicing. All 2600 family modules employ two-piece mating connectors for quick connections to field wiring. External termination boards are not required, as all field wiring connects directly to the modules. This helps to minimize intermediate termination systems and wiring, thereby reducing both material and assembly costs. Input Debounce The module applies a 10 millisecond software debounce filter to all input SSRs. Input debouncing helps to minimize errors resulting from the mechanical switch bounce that is often exhibited by mechanical contacts. PWM Output Each output SSR may be explicitly controlled by the Ethernet client or it may operate as a PWM (pulse width modulated) output, with rate and duty cycle specified by the client. This feature greatly simplifies the closed-loop control of devices such as electric heaters by removing the time-critical burden of PWM generation from the network and host computer. Visual Status Indicators The 2652 and 2653 modules include a number of LED indicators that provide quick visual status of the module:
Models 2652 and 2653 include five interlock circuits. Each of these interlock circuits conveys a signal that may be interrupted by external safety interlock switches, emergency stop switches, or other similar contacts. Each output SSR, in turn, can be shunt-configured to be enabled by any one of the five interlock signals. An output SSR will unconditionally de-energize when its interlock signal is interrupted, thus ensuring fail-safe deactivation when safety conditions require it. Two connectors are provided for the interlock circuits. One of these connects to the interlock signal sources (typically power supply outputs). If needed, the other connector can be used to pass through the interlock voltages to other modules such as a 2610 digital I/O module or additional 2652/2653 modules. This “daisy-chain” system eliminates the external termination boards that are often required for interlock circuits. Mechanical Series 2600 modules utilize robust, uniform 100-mm wide DIN rail mountable frames that enable the modules to be quickly attached to and detached from standard 35-mm-wide DIN rails. This lowers installation costs because DIN rails, unlike panel mounted products, do not require precise mounting hole positions or time-consuming assembly. All modules in the 2600 family employ open-frame design, with field wiring connectors conveniently located at module edges for easy cable routing into adjacent wiring ducts. This eliminates the expensive module enclosures that are found in many competing products. Other I/O Modules A wide range of I/O module types are available in the 2600 series. Each type of I/O module has a specialized function such as analog I/O, digital I/O, counter/timers, and relays. As with the 2652 and 2653, each of these modules connects to a 2601 communication module with a low-cost category-5 patch cable. Up to sixteen I/O modules, in any combination of module types, may be connected to a 2601.

Software and Manuals The Communication Module implements a high-performance, preemptive multi-tasking operating system and UDP/IP stack in firmware. As a result, it boots up in approximately one second. All of the essential standard network protocols are supported: IP, UDP, ICMP, and ARP. It employs a static IP address that can be programmed by connecting a null-modem cable between a PC and the module’s COM4 serial port. Full-featured Windows 98/NT/2000/XP and Linux libraries are available below in the software development kit, along with comprehensive sample programs.
