The injection patch SPL0676 allows the input to process measurement equipment to be diverted from the input device to test equipment for routine maintenance. The injection patch is available in two different case sizes each with 4-20mA or 1-5V test output.
With the switch in the NORMAL position the 4-20mA input on terminals (1, 3) flows through to the output terminals (2, 4) and ultimately to the input of the main plant equipment. This is the normal operating position.
With the switch in the INJECT position a 4-20mA signal is injected through the top mounted INJECTION sockets. This signal will flow through to the output terminals (2, 4) and ultimately to the input of the plant equipment under test. The normal 4-20mA input (1, 3) is terminated by a 100 ohm resistor. This is the maintenance mode of operation.
The output of the injection patch can be monitored on the top mounted TEST sockets. The output test sockets are operational in both inject and normal modes. The 4-20mA output is available in two signal types;
Types A and D has 4-20mA on the test output sockets. This is measured with a digital multimeter on a current measurement range.
Types B and C have a 1-5V signal representing 4-20mA on the test output sockets. This is measured with a digital multimeter on a voltage measurement range.

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 7 days.
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.
