The SMC30 Sensor Module Cabinet-Mounted is required to evaluate the encoder signals of motors without a DRIVE‑CLiQ interface. External encoders can also be connected via the SMC30.

The following encoder signals can be evaluated:

• Incremental encoders TTL/HTL with/without open-circuit detection (open-circuit detection is only available with bipolar signals) (1)
• SSI encoder with TTL/HTL incremental signals
• SSI encoder without incremental signals

The motor temperature can also be sensed using a PTC thermistor KTY84‑130, Pt1000 1) or PTC.
(1) The Pt1000 sensor is not supported when combined with a Control Unit CU305.

Design
The SMC30 Sensor Module Cabinet‑Mounted features the following connections and interfaces as standard:

• 1 encoder connection including motor temperature sensing (KTY84‑130, Pt1000 1) or PTC) either via SUB-D connector or via terminals
• 1 DRIVE-CLiQ interface
• 1 connection for the electronics power supply via the 24 V DC supply connector
• 1 PE/protective conductor connection

The status of the SMC30 Sensor Module Cabinet-Mounted is indicated via a multi-color LED.

The SMC30 Sensor Module Cabinet-Mounted can be snapped onto a TH 35 standard mounting rail in according to EN 60715 (IEC 60715).

The maximum encoder cable length between SMC30 modules and encoders is 100 m. For HTL encoders, this length can be increased to 300 m if the A+/A- and B+/B- signals are evaluated and the power supply cable has a minimum cross-section of 0.5 mm2.

The signal cable shield can be connected to the SMC30 Sensor Module Cabinet‑Mounted via a shield connection terminal, e.g., Phoenix Contact type SK8 or Weidmüller type KLBÜ CO 1. The shield connection terminal must not be used as a strain relief mechanism. 

Integration
SMC30 Sensor Modules Cabinet-Mounted communicate with a Control Unit via DRIVE-CLiQ.
