Notes:
WARNING
If Digihelic®II Controller is powered by 24 VDC, the device receiving the 4-20 mA transmitter output MUST NOT share a common ground with the 24 VDC supply or damage to the Digihelic®II Controller will result.
1. The instrument may be powered from the AC line or 24 VDC. Do not wire AC line terminals 1-2 on the lower board and 24 VDC terminals 4-5 on the upper board at the same time or damage to the unit will result.
2. For supply connections, wire in accordance with an equivalent national standard or code. Use copper conductors only rated for at least 75°C.
3. Terminals on upper board are rated CLASS 2.
4. ISOLATION:
Relays - 1500 VAC to all other inputs and outputs. AC Line Power (terminals 4-5) - 1500 VAC to all other inputs and outputs. RS485 output - 500 VAC to all other CLASS 2 wiring. The 24 VDC Power, 4-20 mA transmitter, and Remote Reset Switch share a common ground.
5. The Remote Reset Switch must be a dry contact switch.
6. Shielded cable is required for RS485 wiring.
3
When wiring the instrument, you must follow industry standard practice for control and

protection against Electro-Static Discharge (ESD). Failure to exercise good ESD practices may cause damage to the control.
WIRING
1. Remove cover.
2. To gain access to the wiring terminal blocks, remove the upper and lower screws toward the center of the display board, and then flip the display board up at a 90° angle.
3. Wire to the two terminals blocks as shown in the wiring diagram.
Note: Depending on the application, it may be only necessary to wire to the smaller terminal block on the upper board. In that case one of the liquid tight fittings may be removed and replaced with the provided rubber plug.
4. For liquid tight applications, use only 1/2˝ liquid tight conduit.
5. When wiring is complete, reverse steps 2 and 1. Make sure the cover is properly tightened to the housing.
DIGIHELIC® II CONTROLLER RS485 WIRING
INSTALLATION
Mount the instrument in a location that will not be subject to excessive temperature, shock or vibration.
Pressure Connections
Use 1/8 male NPT fittings. When tightening fittings, grasp the brass fitting on the Digihelic with a 1/2˝ wrench to prevent the fitting on the Digihelic®II Controller from turning.
