A.1.3 Comparison of Control Circuit Terminal Block
 Spring clamp type terminal block is used for control circuit terminal block of both WJ200 and
WJ-C1, and the recommended wire diameter and terminal are the same. For details, refer to
"5.4.2 Recommended Wire Diameter and Wiring Method for Control Circuit Terminals".
■ Comparison of control circuit terminal block arrangement
WJ200
WJ-C1
* Terminals that have been added/changed electrical characteristics/changed functions compared to
WJ200 are outlined in white.
For those whose terminal symbols only have been changed, refer to the following comparison table.
* The following terminals have the same function/electrical specifications, but the terminal symbols have
been changed. Be careful when switching wiring.
Voltage input [O] ⇒ [Ai1], Current input [OI] ⇒ [Ai2], Pulse input [EA] ⇒ [8]
Analog output [AM] ⇒ [Ao1], Pulse output [E0] ⇒ [Ao2]

Safety function STO input terminals [ST1] and
[ST2] have been added as dedicated terminals.
In addition, [P24S] and [CMS] have been added
as dedicated power supply for functional safety.
Refer to "14.1 Using the Safety Function STO
(Safe Torque Off)" for more information.
