Overview
The B7AM-8B31 is an Omron B7A-series I/O module, order code B7AM-8B31, providing 8 digital inputs and 8 solid-state outputs on a 24 V DC supply. It mounts to either a chassis or DIN rail and terminates through screw terminals, operating across -10°C to 55°C.
Function & operation
The module handles 8 digital input channels and 8 solid-state output channels in a single package. The solid-state outputs switch without mechanical wear, suited for high-cycle applications like solenoid valves or indicator lamps. Screw terminals simplify field wiring, and the dual mounting option — chassis or DIN rail — fits both panel layouts and retrofit scenarios. Rated at 24 V DC, the module draws its operating power from the same supply as the input field devices. The -10°C to 55°C temperature range covers most indoor industrial environments without forced cooling.
Applications
As a compact I/O slice, the B7AM-8B31 fits into Omron B7A remote I/O racks for machine control, packaging lines, and material-handling systems. The 8-input / 8-output count handles a small cluster of sensors and actuators — limit switches, photo-eyes, and small relays — without an additional expansion unit.
