General Description
TC201 is one of the new generation of
Intelligent Communication Thyristor PhaseAngle Trigger Modules. Using the RS485
communication link via any standard PC, up to
254 separate loads can be controlled. Each
load can have up to 1024 control levels of
resolution.
Alternatively, each thyristor controlled load
can be varied by an externally connected
potentiometer, providing a variable 0-5Vdc
analogue input to the TC201. When the 05Vdc I/P terminal of the TC201 is switched to
the wiper of an external potentiometer, the 05Vdc I/P input will automatically over-ride the
phase-angle trigger level from the RS485
Communication
Up to 255 trigger units
can be connected
Windows Based Software
Available
The TC201 supports digital communication based on RS485 multi-slave bus configuration
using two wires. The bus master is usually a PC with a serial RS485 communication port. Each
TC201 connected to the RS485 bus acquires a unique address from the bus master during the
setup phase. The addressing scheme allows a maximum of 255 units to be connected on the
same bus. The communication protocol supports various commands that allow each TC201
output level to be set by the master, status interrogation, or change of configuration.
The following commands are supported:
Level:
The output level of the TC201 can be set by the master between 0 to 1023.
Status:
50/60Hz - the mains frequency detected.
local/remote - local if the analogue I/P is connected.
softstart cycle - the number of cycles used to ramp the output from 0 to setpoint during
power up or when the zero crossing pulse is re-established. The range is 0 to 100
cycles.
setpoint filter - (0 to 10) the number of cycles used to filter the setpoint step changes.
Configuration:
softstart cycle - the number of cycles used to ramp the output from 0 to setpoint during
power up or when the zero crossing pulse is re-established. The range is 0 to 100
cycles.
setpoint filter - (0 to 10) the number of cycles used to filter the setpoint step changes.
