WМ240 Addressable Input-Output Device

WM240D addressable input-output module (I/O device)

WM240 Addressable Input-Output Device (PCB)

The WM240 addressable input-output device with 4 monitored inputs and a built-in short-circuit isolator is designed to transmit the dry contact input state to the control panel and detect open and short circuits in the supervised device circuit.

Available in models:

WM240 - as a printed board to fit in a housing
WM240B - in wall-mount housing
WM240D - in 35 mm DIN rail mount housing
