Relay outputs
The MTX-DIN modem has four 1-form-C (SPDT) relays with a contact rating of 6A, 250VAC/24VDC.
The contacts of each relay (Common, Normally Open and Normally Closed) are available on the
terminal block connector’s pins 5 to 16. All relays are controlled with module’s GPIOs as shown in
table below:
Relay
GPIO number
RL1
GPIO 1
RL2
GPIO 2
RL3
GPIO 3
RL7
GPIO 7
To activate the relay, a logic-1 must be set at the corresponding GPIO module. When the relay is
activated, a LED indicator will illuminate.
