High-Capacity Module without Relay Card
If you want to configure the 1586A yourself to work with the 1586-2586 High-Capacity Module, you will need a relay card. However, if you already have a slot in the back panel of the 1586A configured for use with the 1586-2586, then you don’t need another relay card.
You can simply slide the 1586-2586 High-Capacity Module into the preconfigured slot and begin taking measurements. The 1586-2586 High-Capacity Module is designed with universal input channels to measure temperature, resistance, dc voltage, and dc current for data acquisition applications where channel count and scan speed are important.
Universal input channels designed to measure temperature, resistance, dc voltage, and dc current for data acquisition applications on the factory floor where channel count and scan speed are important.
The 1586-2586 High Capacity Input Module (the Input Module) is used to wire inputs of various types to the Product. Each Input Module has 20 analog channels (ChX01 through ChX20) that can be configured to measure temperature, resistance, and dc volts and two low-burden current channels (ChX21 and ChX22) that measure dc current without the use of an external shunt resistor.
Note: To expand the functionality of the Product, current sources can also be connected to channels ChX01 through ChX20 by the use of an accessory shunt resistor. See Chapter 6 for part number and ordering information.
