Outputs and Inputs
thermoMETER CTL
8.3 Relays Outputs
The thermoMETER CTL can optionally be equipped with a relay output. The relay board is installed the same
way as the digital interfaces, see 8.2.
Connect the external electrical circuit with the terminal blocks.
A simultaneous installation of a digital interface and the relay outputs is not possible.
The relay board provides two fully isolated switches, which have the capability to switch max 60 VDC/42 VAC
RMS, 0.4 A, DC/AC. A red LED shows the closed switch.
The switching thresholds correspondent with the values for alarm 1 and 2, see 8.5 , see 8.5.2 and are factory-
set, see A 2:
Alarm 1 = 30 °C/ norm. Closed (Low-Alarm) and Alarm 2 = 100 °C/ norm. open (High-Alarm).
The adjustment of the alarms can result from the modification of the alarm 1 and alarm 2 via the program-
ming keys.
To make advanced settings (change of low- and high alarm) a digital interface (USB, RS232) and the Com-
pactConnect software is needed.
