E5CD-B-800 (Push-In Plus Terminal Blocks)
Note: 1. The application of the terminals depends on the model.
2. Do not wire the terminals that are shown with a gray
background.
3. When complying with EMC standards, the cable that
connects the sensor must be 30 m or less.
If the cable length exceeds 30 m, compliance with EMC
standards will not be possible.
4. Refer to
E5
@
D-B (Push-In Plus terminal block types)
on
page 48 for wire specifications and wiring methods.
5. Common terminals are indicated with
asterisks (*).
You can use the input power supply and
communications common terminals for
crossover wiring.
Controllers given below if you use
crossover wiring for the input power
supply.
100 to 240 VAC Controllers: 16 max.
24 VAC/VDC Controllers: 8 max.
6. Due to UL Listing requirements, use the E54-CT1L or E54-CT3L
Current Transformer with the factory wiring (internal wiring).
Use a UL category XOBA or XOBA7 current transformer that is UL
Listed for field wiring (external wiring) and not the factory wiring
(internal wiring).

Use non-voltage inputs for the event
inputs.
The polarity for a non-contact input
is indicated by “(
-
).”
Relay output
250 VAC, 3 A (resistive load)
Voltage output
(for driving SSR)
12 VDC, 21 mA
Linear current output
0 to 20 mA DC
4 to 20 mA DC
Load: 500 Ω max
Relay outputs
250 VAC, 2 A (resistive load)
Control output 1
Auxiliary outputs 1, 2
The E5CD-B is set for a K-type thermocouple (input type = 5) by
default. An input error (
s.err
) will occur if the input type setting does
not agree with the temperature sensor. Check the input type.
