Description

Basic Hardware Information

‑ Input channels: 15 single‑ended current‑only inputs, single‑group common return ‑ Signal range: 4‑20 mA (jumper removed), 0‑20 mA (jumper installed) ‑ ADC resolution: 15‑bit; 0.5 µA per LSB under 4‑20 mA mode ‑ Update cycle: Maximum 7.5 ms for full‑15‑channel scan ‑ Accuracy: Typical ±0.3 % full‑scale @25 ℃; maximum ±1.0 % full‑scale over 0‑60 ℃ range ‑ Input impedance: 100 Ω ‑ Isolation rating: 250 VAC continuous group‑to‑backplane isolation; 1500 VAC‑1 min withstand; no inter‑channel isolation ‑ Backplane power consumption: Max 100 mA @5 VDC, powered entirely by VersaMax carrier backplane ‑ Mechanical: Single‑slot module, compatible with IC200CHS022 terminal base; supports hot‑swap operation under powered rack condition ‑ Status indicators: Front‑panel OK LED for module health and internal field‑side power status ‑ Operating ambient temperature: 0 ℃ ~ +60 ℃; storage temperature ‑40 ℃ ~ +85 ℃; relative humidity 5‑95 % non‑condensing ‑ Software configuration: Programmed via Proficy Machine Edition; supports digital filtering, fault‑state output definition.

Core Functions & Features

1. Acquire standard 4‑20 mA analog loop signals from field transmitters, convert analog current into digital engineering‑value data for the VersaMax controller.
2. Open‑wire detection available under 4‑20 mA mode; reports open‑circuit loop fault to CPU for alarm handling; open‑wire diagnosis does not work under 0‑20 mA range.
3. Built‑in 24 Hz analog low‑pass filter suppresses high‑frequency field noise.
4. Supports configurable fault‑state behaviour: hold last valid value or set predefined default value when module fault occurs.
5. Producer‑consumer backplane communication mode; analog input data can be shared between controllers within same VersaMax rack.
6. Hot‑swap‑capable hardware allows module replacement without shutting down rack power.

On‑site Installation & Commissioning Notes

1. Snap module firmly onto IC200CHS022 carrier base. Hot‑swap is permitted, yet cut off field transmitter loop power during replacement for safety.
2. Confirm jumper setting on terminal base matches actual field transmitter current range. Missing or fitted jumper will lead to reading offset if mismatched with field equipment.
3. Use shielded twisted‑pair cables for analog signal wiring. Separate analog cables from high‑voltage power cables to reduce electromagnetic interference; single‑point shield grounding is recommended. All 15‑channel negative return terminals connect to common A17 terminal on RTB base.
4. Complete hardware configuration inside Proficy Machine Edition software, enable diagnostic functions according to site requirements.
5. After wiring and configuration, perform signal injection test with calibrator to verify channel reading and open‑wire diagnostic response.
6. Replacement note: This module has no channel‑to‑channel isolation. Isolated analog input modules cannot serve as direct drop‑in substitutes without project re‑configuration. Use identical part‑number replacement.

Common On‑site Abnormal Conditions

‑ Deviated or fixed reading: Wrong jumper range setting on carrier base, loose RTB terminal connection. ‑ Open‑wire fault alarm (4‑20 mA mode): Broken field loop cable, loss of 24 V loop power for transmitter or loose terminal contact. ‑ Signal jitter and fluctuation: Insufficient digital filter parameter, poor cable shielding or strong nearby electromagnetic interference. ‑ OK LED off: VersaMax backplane power abnormality or internal module hardware damage. ‑ Intermittent channel anomaly: Module not fully latched onto carrier‑base socket, vibration‑induced poor contact.
