PLCs, Power Supplies & Others

This analog output module converts digital commands into precise analog signals for field devices. It integrates seamlessly into the Fuji Electric SPH series programmable controller platform. The unit drives up to two independent output channels from a single rack slot. Users can control valves, actuators, and variable-speed drives with high accuracy.

Output Channel Configuration and Signal Ranges

This module features two isolated analog output channels for flexible system integration. Each channel provides configurable current output from 4 mA to 20 mA for standard actuators. Users can also select voltage output ranges of 0 V to 10 V or -10 V to +10 V. The resolution reaches 12 bits for fine-grained control signals. Each channel includes short-circuit protection for reliable operation.

Signal Conversion and Accuracy Performance

The NP1AYH2-MR achieves a resolution of 12 bits for accurate signal representation. Accuracy reaches ±0.2% of the full-scale range at 25 °C ambient temperature. Temperature drift remains below ±50 ppm/°C for stable industrial performance. The module updates each output channel with a settling time of 1 ms for responsive control. This precision supports demanding process control applications with tight tolerance requirements. Consequently, users achieve consistent product quality and reduced material waste.

Output Protection and Diagnostic Capabilities

This output module integrates comprehensive protection features for each channel. Short-circuit protection limits output current to safe levels during wiring faults. Over-temperature protection shuts down affected channels during thermal overload. The module also performs open-circuit detection on current output channels. Diagnostic status reports back to the PLC for continuous monitoring. Operators receive immediate alerts for any output-related issues through the CPU.

Backplane Communication and Configuration

This module communicates with the SPH CPU through the dedicated backplane bus. It supports both local and remote rack installations for flexible architecture. Users configure output ranges and scaling through the standard programming software. The unit stores configuration parameters in non-volatile memory for automatic reloading. Additionally, each channel allows independent scaling for different actuator requirements. This flexibility accommodates various field devices within a single module.

Energy Consumption and Thermal Management

The module draws 40 mA at 5 V DC from the backplane for internal logic. The unit consumes approximately 50 mA at 24 V DC from the field supply. Total power dissipation remains below 2 W under full operational load. Natural convection cooling maintains safe temperatures across all output channels. Consequently, the operating range spans 0 °C to 55 °C for standard factory environments. Humidity tolerance reaches 10% to 90% without condensation concerns.

Installation and Wiring Simplicity

This module features a removable terminal block for convenient field wiring connections. Installers can pre-wire the connector before inserting it into the rack slot. The unit accepts wire gauges from 0.2 mm² to 1.5 mm² for flexible installation. A locking mechanism secures the module against vibration and shock. Furthermore, the housing carries an IP20 rating for protection against solid objects. This robust design suits chemical processing, water treatment, and material handling applications.
