SI289 - Signal Isolator
The SI289 is a isolating transmitter designed for factory set input output combinations providing true 3-way galvanic isolation up to 2000V rms.
The wide range ac/dc power supply is magnetically coupled to both the input and the output circuit section separately, achieving power/input/output isolation. Input signals are transferred optically to the output stage.
The standard Signal Isolator will accept DC voltage or current input signals directly (0.1V up to 2kV, 1mA up to 10A). Final calibration is trimmed using the front accessible ZERO and SPAN 15-turn trim adjustments.
The output signal level is indicated by a green LED on front of the module, giving a clear indication of module function, signal presence and loop condition for current outputs. Reverse or direct action are factory configured.
Special requirements for input/output response time variation can be accommodated by optional “customised response” or “output ramp” models.

Lead Time for a Traditional Product
Traditional products usually contain the same functionally as standard and premier products but have a different connection, part number or specifications. Traditional products are still available as a service to our customers that have them specified in their plants. Delivery is typically 10 days.
Order Processing
APCS makes and customises products according to a customers order. Upon receipt of the customers order the following information is required before manufacture, allocation or deliver until full details are given, these include;
- Identity of purchaser. Company name, ABN (Australian companies), street address and accounts email address.
- Required delivery address.
- Full part number and calibration detail required to manufacture items.
- Total on purchase order to include delivery charges. Orders received with missing information will be entered and marked to indicate missing details and returned to the customer for correction or approval.
Compliance with the above ensures that your items are manufactured and delivered according to the required specifications.
Standard delivery times commence after the order has been approved for processing.
