USE AUX. POWER OUT (PINS C OR D) TO POWER THE KEYSWITCH INPUT AND THE STATUS OUTPUT LOAD,
WHEN NEEDED.

THE STATUS OUTPUT IS A LOW-SIDE SWITCH THAT CAN BE OPERATED AT A MAXIMUM OF 42 V AND 500 MA.
THE MINIMUM WIRE SIZE FOR PINS W AND Z (POWER SUPPLY INPUTS) IS 16 AWG. FOR ALL OTHER I/O, THE
RECOMMENDED WIRE SIZE IS AT LEAST 18 AWG.
SHIELDING FOR THE ANALOG INPUT IS OPTIONAL

THE SHIELDING FOR THE ANALOG INPUT (OPTIONAL) AND FOR THE PWM INPUT SHOULD BE TERMINATED AT
THE CUSTOMER END.
Figure 2-5. TecJet 52 Wiring Diagram
All signal and I/O wiring on the TecJet 52 is not to exceed 30 m (100
ft) in length. See “Supply Voltage” section for specific wire length
limitations on the power supply inputs.
When wiring to pins V and/or J on the TecJet 52, be careful to ensure
that the external circuit interface is isolated from battery ground,
either by means of galvanic isolation or differential input/output.
If it is not, a ground loop could be formed that can cause excess
noise on the lines and/or damage to circuits.
