Availability: In stock
SNAP 2-Ch 10-Ohm Copper RTD Analog Temperature Input

Production Specification

The SNAP-AIRTD-10 provides two channels of analog temperature input. Nominal input range is -180 to +260 degrees C. Although the two channels are not isolated from each other, the module is transformer isolated and optically isolated from other modules and devices. Modules are factory calibrated.

Part of the SNAP PAC System, the module mounts on a SNAP PAC rack with a SNAP PAC brain or rack-mounted controller. Analog, digital, and serial I/O modules can all be on the same rack. Such an I/O unit is also well suited for PC-based control or for use as intelligent remote I/O for an Allen-Bradley Logix PLC system, such as ControlLogix, MicroLogix, or CompactLogix.

The SNAP-AIRTD-10 uses 10 ohm copper inputs. For other similar modules, see the SNAP-AIRTD (100 ohm platinum) and the SNAP-AIRTD-1K (1000 ohm platinum).

Build your system in the SNAP I/O Configurator.
