Designed in a compact DIN rail or wall mount housing, the AMGFIB series provides digital transmission of one serial data and three contact closure channels for remote input detection and relay control. The serial data channel supports one RS422 or RS485 data channel in 2-Wire and 4-Wire mode in both directions. The three contact closure channels support two channels in the forward direction (A to B) and one channel in the reverse direction (B to A). Fitted with dual redundant power inputs supporting both DC and AC low-voltage inputs ensures maximum operating reliability and the highest levels of performance. A wide range of models are available to suit all design requirements. PSUs need to be ordered separately.
