Relay: RLlnA and RLnB are normally open;
RLnA and RLnC are normally closed
Wiring method:
Grounding requirements: 1. First, the ground terminal of the instrument must be connected to the
ground. Do not share the ground terminal with other equipment.
3. The ground resistance must be less than 4 ohms.
2. Connect to No. 4 terminal.
Transducer: Red wire: Connect Trans1 transducer Blue wire: Temp 1 + Temperature
Black wire: GND ground wire
Current output: "C" connected to mA1 +; "Current-" connected to mA- / GND
If the default state of the relay is "normally open", the wiring is connected to RLlnA
and RLnB.
If the default state of the relay is "normally closed", the wiring is connected to RLlnA
and RLnC.
Power cord: power is AC: connect L, N
The power source is DC: 24V + to 24VDC +, 24V- to 24V DC-.
