GE Fanuc IC694ALG391

The GE Fanuc IC694ALG391 is a high-performance two-channel analog current output module designed for use within the RX3i PACSystems architecture. Each channel of this module can convert up to 12 bits of binary data into precise analog signals, supporting output ranges of 0 to 20 mA and 4 to 20 mA, configurable via jumpers. For applications requiring voltage outputs, users can implement a 250 Ohm resistor in place of a voltage jumper, with operational voltage ranges of 1-5 V and 0-5 V available. Powering the module necessitates an external isolated +24 VDC source, which connects via the TB1 connector or directly to the terminal block. Notably, for maintaining output values in the event of backplane power loss, an external power supply is also required. The module features an update rate of 5 milliseconds per channel, depending on application demands, and ensures optimal performance through the use of high-quality twisted, shielded instrumentation cables to mitigate noise and capacitive loading. The IC694ALG391 includes an LED indicator for module status, facilitating system diagnostics. This module is compatible with both Series 90-30 and RX3i serial expansion backplanes, making it a versatile choice for complex industrial automation systems.
