Digital I/O Module with CAN interface, IOC-002

24V digital input/output module with CAN-Bus interface
as a parallel I/O extension of control systems

Abstract
With the input/output module IOC-002, control systems like i.e. Traffic Light Controller TLC-LED can be upgraded via CAN bus with a 24V parallel-interface. This allows additional functions like on-site-emergency control or a second (redundant) control path.

Features

Processing of 8 inputs and 8 outputs with 24V levels
Electronical disconnection of the push-pull outputs in case of overload
Control and communication via CAN bus
Operation with 24 DC (reverse polarity protection)
Up to 8 modules (64 I/O) addressable on the same CAN bus
Extended temperature range (-20 to +70°C)
Easy DIN rail installation
All connections pluggable with clamp blocks

Functional Description
The IOC-002 Module serves the processing of parallel digital signals with a level of 24V DC. Each level change of an input is transferred by CAN bus immediately and is available for all connected bus-participants. The levels of an output can be controlled by all connected bus-participants. The output drives the connected load independently of the chosen level (Push/Pull). To prevent short circuits and/or overloading the outputs are monitored and switched off in case of emergency. Switched off outputs are neither connected to the OV nor to the 24V potential of the supply, i.e. they are left floating (Tri-State). The disconnection of an output is reported on the CAN bus and available to all bus-participants. Up to 8 IOC-002 can be operated on the same CAN bus. Addressing is configured by means of a DIP switch. This allows the use of up to 64 inputs and outputs. All inputs and outputs as well as the system state and the communication on the CAN bus are indicated on the board by corresponding LEDs.
