Technical Specifications: The module provides twelve single-ended channels arranged in one group. Default output signal is 4-20 mA, configurable to 0-20 mA via jumpers. Resolution is 13-bit. Output current per channel is approximately 20.38 mA for driving loads. External power supply range is 18-30 VDC. Backplane current consumption is 50 mA from the +5V bus. Update rate is 15 milliseconds. Isolation rating is 250 VAC continuous and 1500 VAC for one minute between user input and logic or frame ground.
Functional Features: Jumper-configurable output range switching between 4-20 mA and 0-20 mA. LED indicators include FLD PWR for field power presence and OK for backplane power presence. Low backplane power consumption of 50 mA contributes to system energy efficiency.
Application Scenarios: Chemical dosing systems, precise motor speed regulation, process control valves, actuator banks, and multi-zone temperature control systems.
Performance Parameters: 13-bit resolution ensures high-precision analog output. Isolation capabilities protect against electrical noise in harsh environments. Update rate of 15 ms provides responsive control for most industrial processes.
Material Composition: Industrial-grade housing with protected circuit boards and screw-clamp terminal compatibility.
Structural Characteristics: Single-slot VersaMax module form factor. Twelve channels in one group simplify wiring for high-density applications.
Working Principle: Digital output data from the host CPU or NIU is converted to analog current signals by internal DAC circuitry. Each channel operates as a current source, supplying regulated current to the connected load.
Installation Requirements: Install on VersaMax box-style or compact carriers. Connect external 18-30 VDC field power. Configure jumpers for desired output range before applying power.
Usage Precautions: External power is required for proper operation. Verify jumper settings before startup. Use shielded cables for analog outputs in high-noise environments. Do not mix voltage and current signals on the same wiring bundle without proper shielding.
