Accessories

TEC99001 = Smart Network Adapter for third party software,

converts 255 channels
of RS-485 or RS-422 to RS-232 Network

TEC99001 = Smart Network Adapter for programming port to
RS-232 interface 
TEC99030 = Configuration Software 

The TEC-410 limit control is an over temperature protec-
tion or a high limit safety device with a latching output that
removes power in an abnormal condition when the process
temperature is higher than the high limit set point or lower
than the low limit set point.

The unit is powered by 11–26 or 90–250VDC/VAC supply,
voltage incorporates a 3 amp form C relay for limit control,
a universal input which is fully programmable for PT100,
thermocouple types J, K, T, E, B, R, S, N, L, and 0-60mV,
and an option port is available for one of the following
functions: RS-232, RS-485 communication interface and
Retransmission. Alternative output options include SSR
drive and triac. The input signal is digitized by using an 18-
bit Analog to Digital converter. Its fast sampling rate (5
times/second) allows the TEC-410 to control fast processes
such as pressure and flow in addition to temperature.

RS-485 digital communication is available as an additional
option. This option allows the TEC-410 to be integrated
with a supervisory control system. An alarm output is

another option. A variety of alarm functions and alarm
modes can be programmed for a specific application. The
DC power supply output option is used for an external sen-
sor or transmitter. The standard event input option can be
programmed for remote reset or remote lock out signal
input. The limit annunciator option can be used to control
an alarm buzzer.

Three different methods can be used to program the
TEC-410.
1. Use the keys on the front panel to program the unit

manually

2. Use a PC and setup software to program the unit via the

RS-485 port.

3. Use a PC and configuration software to program the

unit via the programming port.

High accuracy, maximum flexibility, fast response, and user
friendly operation are the main features of the TEC-410
high limit controller.
