Frequency/Tachometer/Line Speed Meter with Analog Retransmission, RS-485 and 2 Relays, 230 V Powered
5 digit tachometer / line speed / frequency meter with 2 alarm relays, analog retransmission and RS-485. 100 to 240 VAC/DC powered.
The DC5H/AM5H series are budget priced 5 digit panel meters which can be configured to operate as a tachometer, line speed meter or frequency meter. This model features 2 alarm relays, a 4 to 20 mA analog retransmission signal and a RS-485 Modbus connection.
The meter can be configured to show frequency, RPM or line speed (counting pulses from a line-following wheel or drum of configurable diameter). The unit comes with a large range of stickers for the front panel including RPM, M/min and kHz.
Line speed and RPM values can be measured using a wheel or drum sensor. The meter can be configured for sensors outputting 1 to 99,999 pulses per revolution. In line speed mode, the drum diameter can be set from 0.0001 to 9.9999 meters.
The analog output can be used to retransmit the displayed value. User-configurable high and low points allow the scaling to be changed. The polarity of the scaling can be switched for 20 to 4 mA output.
This unit has an RS-485 serial port and communicates via Modbus RTU. The displayed value can be monitored and all settings can be modified by writing to holding registers.

Input signal:
The signal input for this meter can come from a range of NPN/PNP or dry contact sensors. An external excitation voltage is supplied at the back of the unit for sensor power. As shipped from the factory, the unit is configured for 12 VDC excitation supply and NPN or dry contact input. Internal jumpers can be moved to set 5 VDC excitation or PNP input type.
A separate jumper enables a low pass filter, useful for input frequencies less than 100 Hz. By default, the unit ships with the full 100 kHz input frequency range available.
Display units and modes:
The SCALE and PPR (Pulse per Revolution) settings allow the input frequency to be scaled to just about any units desired. The meter has some functions built in that make common scaling configurations easy.
The type setting applies fixed scaling appropriate for direct frequency display (no additional scaling), RPM display (scales pulses per second to pulses per minute) and line speed, which scales pulses accounting for the diameter of a pickup wheel or drum.
- Frequency: Displays input frequency / PPR setting × SCALE setting
- RPM: Displays input frequency × 60 / PPR setting × SCALE setting
- Line speed: Displays input frequency × 60 / PPR setting × SCALE setting
A second scaling setting is activated when in line speed mode. The drum or wheel diameter (set by the SCALE parameter) is configured in meters, but by setting the UNIT parameter, the display can be set to show line speed in meters/min, yard/min or feet/min.
