MeloAuto-Trusted PLC & DCS Parts Supplier
The ABB Bailey NIAC03 provides precision calibration signals for analog input testing. This module generates stable reference voltages and currents for channel verification. It weighs approximately 0.72 kg and mounts on a standard DIN rail. Its dimensions measure 25.4 cm in length, 12.7 cm in width, and 5.1 cm in height.
Technical Specifications & Hardware Details
The NIAC03 features two independent calibration output channels with high stability. A single 24-pin ribbon cable header connects this module to the host I/O system. This unit stores no energy internally because it contains no batteries. Four main components form the complete assembly: the PCB, the terminal block, the reference generator, and the cable connector.

Calibration Capabilities and Field Use
You can connect the NIAC03 directly to analog input modules for field calibration. Each output channel provides stable reference signals without external equipment. For voltage output, use twisted-pair wiring to maintain signal integrity. The module also includes short-circuit protection on both output channels.
Installation and Operational Data
You can install this calibration module inside any standard control cabinet. The unit draws 150 mA from an external 24V DC power supply. Furthermore, it operates reliably within a 0°C to 55°C temperature range. Consequently, the NIAC03 requires annual accuracy verification for best performance. Simply recalibrate using a certified multimeter as a reference.
