The following table describes the terminals on the H1 interface card PR‑10701 and on the transmitter motherboard PR‑10600.

Terminal Usage
On H1
A 1 2 3 Connection for Sensor A, signal wires (1, 2), cable shield (3).
B 1 2 3 Connection for Sensor B, signal wires (1, 2), cable shield (3).
On motherboard
11 12 4 … 20 mA output 1, positive (11), negative (12), max. load 1000 Ω, galvanically isolated.
13 14 4 … 20 mA output 2, positive (13), negative (14), max. load 1000 Ω, galvanically isolated.
21 221 Relay 1, one contact output, max. 240 V AC, max. 3 A, fuse with voltage 250 V AC, max fuse size 3 A, speed slow.
23 241 Relay 2, one contact output, max. 240 V AC, max. 3 A, fuse with voltage 250 V AC, max fuse size 3 A, speed slow.
31 32 331

Power, L (31), N (32), protective earth (33), 100 … 240 V AC, 50 … 60 Hz, fuse with voltage 250 V AC, max. size 10 A and speed slow. An external power switch is mandatory.

Power, + (31), - (32), protective earth (33), 24 V DC ± 10%, fuse with voltage min 48 V DC, max. size 4 A and speed fast.
41 42 24 V terminal for DTR internal use only.
Connecting terminal to external 24 V supply voids the warranty. Connecting external devices to 24 V terminal voids the warranty.
51 52 53 54 55 Switch inputs: switch 1 (51), switch 2 (52), switch 3 (53), switch 4 (54) and common 3 V for all inputs (55). The switch terminals are galvanically isolated.
  1. To access the electrical terminals, open the enclosure cover.
  2. Loosen the front panel screw (2), and open the front panel.

    All terminals are now accessible.

    1. Power indicator light
    2. Front panel screw
  3. Connect the signal wires to terminal (1) and (2), and the cable shield to terminal (3).
    Make sure that you connect the signal wires in the sensor and in the indicating transmitter in the same order.

    • The following figure shows the motherboard of the indicating transmitter for AC power.

    • The following figure shows the motherboard of the indicating transmitter for 24 V DC power.

1 Wiring to terminals should be min. 1.5 mm2 (AWG 18). The fuse voltage should be 250 V, max. size 10 A and fuse speed slow. Torque used is 0.5 Nm … 0.6 Nm. Stripping length is 8 mm for wires.
