Overview

The Trumeter 8981-5 (SKU: 8981-5) is a 6-digit LCD preset counter with dual Form C relays, RS485 interface, and 100-240VAC power supply. Designed for preset, batch, or total counting, it features a 14mm high 14-segment LED display for clear visibility in harsh conditions. The device supports MODBUS RTU and CR/LF protocols over RS485 for remote monitoring and control. Dual relays (277V AC/5A or 30V DC/5A) enable flexible switching. Input modes include pulse counting (up/down, addition, phase discrimination) and rate/timer functions. Housed in a 1/8th DIN enclosure with IP65 front protection, it operates from -20°C to +65°C. Ideal for industrial automation, material handling, and process control.
