12 RTD & 4 Universal Signal Inputs Controller, SAE J1939, 250 kbps
Item # AX184000 — 12 RTD & 4 Universal Signal Inputs Controller, SAE J1939, 250 kbps
The RTD Scanner monitors 12 3-wire or 2-wire RTD inputs from a diesel engine and the temperature information is provided to the engine control system over a SAE J1939 CAN bus. Each channel operates independently. Temperature information can include exhaust temperature, winding temperature, and fluid temperature monitoring. All channels of temperature data are automatically sent over the CAN bus when power is applied with no additional programming or configuration required. Integral diagnostics determine RTD integrity. RTD inputs are isolated from the CAN communication and power supply. 4 universal signal inputs are user selectable as voltage (0-5 V, 0-10 V), current (4- 20 mA, 0-20 mA), PWM (0-10 kHz), counter, or digital (active high, active low, or latched) input types. During set-up, using a USB-CAN converter and a PC, the operator can configure the controller via Axiomatic Electronic Assistant to suit a wide variety of applications.
The RTD Scanner features rugged packaging and watertight TE Deutsch equivalent connectors for an IP67 rating. The RTD Scanner is designed to meet the environmental, EMC, and vibration requirements of generator set applications.

The 12 VDC input power converters operate from a 12 VDC (nominal) battery or other source and provide a clean VDC output power suitable for instrumentation and control networks equipment. For operation under harsh and demanding conditions, the units are fully sealed to protect against moisture, shock, and vibration. Each power converter unit in this category is designed with rugged electrical protections. Nominal nameplate ratings will vary.
