Additional Information
External relay at signal output V(X) (0-10V / PWM)
In order to use a 0-10V / PWM output as a 230V / AC switching output, an external switching relay (Art. No. 77502) can be con-
nect at the output V (X) (V1, V2, ...).
The external relay is then activated via the signal output (0V = "off", 10V = "on").
1. Connect external 0-10V relay to signal output, e.g. V1.
CAN bus
The CAN bus can be used to connect two or more controllers with each other or with the data logger to exchange data.
1. The controllers are connected in series with the CAN bus cable.
2. The first and last controllers in this connection in series must be fitted with terminating
resistance.
The wiring of the two CAN sockets is arbitrary.
3. Optionally, the data logger can also be connected to the CAN bus.
