Key parameters
Slim digital circular chart recorder/controller for one or two process variables — 10 in chart, disposable fiber-tip pens (red/green), universal inputs (TC/RTD/mV/V/mA), 90–264 VAC, optional relays/alarms and RS-485 Modbus RTU, NEMA 3 standard with NEMA 4X option. West Control Solutions lists MRC5000 as obsolete and directs new orders to Specialty Product Technologies.
Key advantages
- Universal inputs — J/K/T/R/S TC; Pt100 RTD; mV/V/mA ranges; field-programmable input type.
- Record / limit / control — record-only or high/low limit and record/control modes.
- 10 in chart — user rotation 8 h / 12 h / 24 h / 48 h / 7 days; 100 charts furnished (0–100 default).
- Compact panel depth — 14×14×3.8 in overall; ~2.5 in panel depth; retrofit plate for MRC7000/ARC4100 cutouts.
- Options — relays, process alarms, RS-485 Modbus RTU, NEMA 4X, door lock, config port.
Typical applications
- Process temperature/pressure recording on circular charts.
- High/low limit recording in regulated processes.
- Panel or wall installations needing shallow depth.
- Retrofits into MRC7000 / ARC4100 cutouts with adaptor plate.
Selection guide
- Pens — one or two disposable fiber-tip (pen 1 red / pen 2 green).
- Inputs — TC/RTD/mV/V/mA; measurement error ±0.25% of span ±1° (TC/RTD) per datasheet.
- Outputs — optional SPDT relays; up to two process alarms per input.
- Comms — optional RS-485 Modbus RTU, 9600 baud.
- Protection — NEMA 3 standard; NEMA 4X optional.
- Availability — West CS marks obsolete; RFQ may route via Specialty Product Technologies (OEM note).
Common mistakes
- Expecting active West CS stock without checking Specialty Product Technologies availability.
- Ordering two-pen features on a one-pen hardware build.
- Skipping NEMA 4X when washdown is required.
- Forgetting chart range/rotation needs (default 0–100, 24 h).
When to RFQ / what to tell us
- 1- vs 2-pen; input types; relay/alarm options.
- NEMA 3 vs 4X; Modbus need; retrofit plate.
- Chart range/rotation; quantity; ship-to.
- Whether replacement vs new installation (obsolescence path).
