GRT1 Series
GRT1-TS2T
Thermocouple input
Terminal block and main block can be
separated.
Hardware DIP switch setting, software Setting Tool. Each input bit can be set up
individually when using the Setting Tool.
R, S, K, J, T, B, L, E, U, N, W, PL2
±2°C, ±1 digit max. (See note.)
250 ms/2 points
The temperature data is multiplied by 100 and sent to the Master as 8-digit
binary data. (The data for each input consists of two words.)
Not supported.
Supplied from slice bus.
None
None
Default: Temperature data for 2 points
The Setting Tool can be used to allocate
the peak value, bottom value, top value,
valley value, rate of change, comparator
results, Status Flags, etc.
No setting required.
No setting required.
Supported. (Set using Setting Tool.)

Supported. (Set using Setting Tool.)
The indication accuracy depends on the mounting direction and the Units on
both sides of and directly next to the GRT1-TS2T. Refer to the following infor-
mation. Refer to Performance Specifications on page 169.
Section 6-1
DRT2 Series
DRT2-TS04T
Removable terminal block
(±0.3% of indication value or ±1°C,
whichever is larger) ±1 digit max.
250 ms/4 points
Supported.
Supplied from communications power
supply.
70 mA max.
Poll, Bitstrobe, and COS/cyclic
Default: Temperature data for 4
points
The DeviceNet Configurator can be
used to allocate peak value, bottom
value, top value, valley value, rate of
change, comparator results, Status
Flags, etc.
Set using the rotary switches or the
DeviceNet Configurator.
Automatically detected: Uses baud
rate set for Master Unit.
Supported. (Set using DeviceNet
Configurator.)
Not supported.
Supported. (Set using DeviceNet
Configurator.)
