Description

Process Panel Meters PM-RM True RMS Meters Shimpo

The Series PM-RM 1/8 DIN True RMS Meters are designed for process automation, offering jumper-selectable AC signal input ranges for versatility. They are fully scalable, displaying readings in desired engineering units and are ideal for use with current and voltage signal transformers. Current input models have 4 ranges (2.0000 mA to 5.000 A) and voltage input models have 6 ranges (200.00 V to 600.0 V). These meters support both AC and DC power options.

Features

Universal power range of 85-264 V ac / 90-300 V dc or 10-48 V dc / 12-32 V ac power eliminates need to purchase country specific models.

Bright, red 5 digit LED display scalable to 99,999 with adjustable decimal point.

Programmable scaling permits usage with current or voltage transformers.

Digital filtering is menu-selectable for electrically noisy environments.

Accuracy of ±0.1% of full scale ±2 counts (LSD).

Choice of 2 relays or 2 solid state relays.

Analog signal option provides: 4-20 mA, 0-20 mA, 0-10 V or -10 V to +10 V outputs.

High read rates at up to 60 or 50 conversions per second.

Peak and valley values are automatically captured and may be displayed via a pushbutton, control signal input, or be transmitted as serial data if a communication option was ordered.
