ET 8E8A

1

Remote Input-/Output Unit ET 8E8A This module enables the management of remote inputs and outputs in complex systems far from the central. Data is transmitted fully digital via 2-wire lines to the central. Managing of 8 inputs with 5 steps and 8 outputs, thereof 4 make- and 4 change-over contacts. Status-LEDs

for all inputs and outputs show the function at a glance, additionally the line from the ET 8E8A to the central is continuously monitored. Mounting is possible in a 19“ rack on a DIN rail or with the supplied mounting rail for wall mounting.

1. ET 8E8A Remote input- / output unit with 8 inputs (5 steps) and 8 outputs (4 make and 4 change over contacts).
