True RMS AC Phase Monitor
True RMS AC phase monitor produces voltage readings for single- and three-phase
power.
H-O-A Switches
The H-O-A switches are fail-safe; they remain operational even if the TCU fails or
loses power. They will continue to function in the “Hand” and “Off” positions with the
TCU in a faulted state or powered down.
Integrated Radio
The TCU’s integrated digital radio is on-site programmable and can run in legacy or a
high-speed mode.
Battery Backup with
Integrated Charger
The TCU supports a 12VDC sealed lead acid battery and a 3 amp maximum current
charger.
Display / Interface
A touch screen LCD provides a large area for displaying data and menu navigation.
One soft-touch home button allows the user to power up/down the TCU with a single
touch, and seven LEDs provide system status at a glance.
Serial Connectivity
Standard RS-232 Modbus radio interface acts as an interface (slave only) to external
industry standard radios.
RS-485 Modbus half-duplex serial interface (master only) enables communication
with industry standard devices and VFD motor controllers.
Network Adapter
An integrated 10/100 network adapter allows remote access via SSH client over a local
area network.
USB/Service Port
Three full speed USB 2.0 ports (2 external/1 internal) storing station address, config-
uration profiles, and pump statistics. Provides Ethernet connectivity with additional
USB-to-ETH adapter.
Protection
Protective features include an integrated, regulated power supply, surge protection,
and isolation on all I/Os, and an externally-accessible fuse.
Protocols Supported
Protocols supported are Modbus (ASCII/RTU) over RS485 or RS232, TAC II and DFP
3.0 over radio and BEM, and DFS NIM and Modbus TCP over TCP/IP.
Pump Run Time Meters
Elapsed run time, average run time, and pump cycle counters are provided in software
for each pump.
Self-Monitoring
Self-monitoring capabilities include radio current, temperature, battery voltage/
charging current, AC power, bias fault, process and error logging with option to backup
to a USB drive.
control and monitor the six onboard digital outputs, 18 digital inputs and four analog inputs. It also features an expansion
card slot
which can be used to add additional I/O points for specialized applications, such as controlling VFD pumps.
