Connection
■ External Connection
• Functional insulation is applied between the power supply and the I/O sections. If reinforced insulation is required, connect the input
• To comply with the standards for noise terminal voltage for class A in EN 61326, install a noise filter (Densei Lamda MXB-1206-33 or
• Use an SELV power supply that provides overcurrent protection. An SELV circuit is one separated from the power supply with double

S8VM or S8VS Series is recommended for the power supply.
Model with Screw Terminals
2. To connect to a computer using the port A connector, use a separately sold E58-CIFQ1 USB-Serial Conversion Cable. The Temperature Controller can be
3. Models with screw-less clamp terminals have terminals A10 and B10, but they are not used. Do not connect anything to them.
Port C
connected to a computer using USB.
RS-485 for port C and RS-232C can be switched.
A separate EJ1 model must be used for
RS-422 communications.
