PLUG-IN POWER SUPPLY MODULES
JH9046-1: Output Adjustable from 1.5 to 15Vdc @ 100mA
JH9046-2: Output Adjustable from 15 to 30Vdc @ 50mA
JH9246: Dual Fixed 24V Outputs @ 25mA Per Channel
- Powers 4/20mA Loops, Strain Gauges, Sensors
- Outputs from 1.5 to 30Vdc Available
- Short-Circuit Protected Outputs
- Uses Standard 8-Pin Socket
JH Technology power supply modules provide regulated and filtered DC supplies. Model JH9046 provides two adjustable voltage range options: 1.5 to 15V at 100mA max. load or 15 to 30V at 50mA. If specified on your order, we’ll adjust the output to your requirements.
JH9246 is a dual-output model designed with 4/20mA 2-wire transmitter loops in mind. Each module is capable of powering two such loops. Its two 24V outputs are isolated from each other, minimizing ground-loop concerns in multi-loop applications.
All three models are internally protected against failure due to short circuits. 115 and 230Vac power options are available.
ORDERING INFORMATION
| Model Number: |
Select from the list above. |
| Output, Model JH9046: |
JH9046-1 is normally factory-set at 5Vdc, JH9046-2 at 24Vdc. If you wish different settings simply specify on your order. We’ll do it at no extra charge. |
| Output, Model JH9246: |
(Nonadjustable. Fixed at 24Vdc +/-4%) |
| Power: |
Specify 115 or 230Vac. |
INSTALLATION AND CONNECTIONS
The power supplies plug into any standard 8-pin circular ("octal") relay socket. JH Technology offers two sockets: DS008 for DIN-rail or surface mounting and ST008 for Snap-Track mounting (see the Accessories page). Pin connections are:
Pin 1: AC Power.
Pin 2: No connection.
Pin 3: AC Power.
Pin 4: No connection.
Pin 5: Output plus, second supply. (JH9246 only. No connection on
JH9046.)
Pin 6: Output minus, second supply. (JH9246 only. No connection on JH9046.)
Pin 7: Output plus.
Pin 8: Output minus.
