Relay module

If two or three measurement modules with relay outputs are being used, an additional (relay)
module can be installed on the unit. This relay module then provides the following additional
switching outputs.
The clamp names differ depending on the design of the relay board
(article number 255123, 255190, or 255199) see fig. 5.2.

All Multronic relay connections have a spark-quenching circuit through which a minimal
residual current can flow even if the contact is open.
