C80 Series Connection and Setup Manual
4 General Specifications
(2) ERR terminal
Q61P/Q64PN
- Turned ON when the whole system operates normally.
- This terminal turns OFF (opens) when the AC power is not input, a stop error (including a reset) occurs in the
CPU module, or the fuse is blown.
- In a Multiple CPU system configuration, turned OFF when a stop error occurs in any of the CPU modules.
- Normally OFF when loaded in an extension base unit.
Q63P
- Turned ON when the whole system operates normally.
- This terminal turns OFF (opens) when the DC power is not input, a stop error (including a reset) occurs in the
CPU module, or the fuse is blown.
- In a Multiple CPU system configuration, turned OFF when a stop error occurs in any of the CPU modules.
- Normally OFF when loaded in an extension base unit.
(3) FG terminal
Ground terminal connected to the shield pattern of the printed circuit board.
(4) LG terminal
- Grounding for the power supply filter.
- This terminal has potential of 1/2 of the input voltage for AC input (Q61P, Q64PN and Q64P).
- This is also a protective earth terminal (PE).
(5) Power input terminals
- Power input terminals connected to a power supply of 100VAC or 200VAC. (Q64PN)
- Power input terminals connected to a power supply of 24VDC. (Q63P)
- Power input terminals connected to a power supply of 100-200VAC. (Q61P)
(6) Terminal screw
M3.5 x 7 screw
(7) Terminal cover
Protective cover of the terminal block
(8) Module fixing screw hole
Used to fix the module to the base unit.
M3 x 12 screw (user-prepared) (Tightening torque: 0.36 to 0.48 Nꞏm)
(9) Module loading lever
Used to load the module into the base unit.
(Note 1) Q63P is dedicated for inputting a voltage of 24VDC. Q63P may break down unless connected to 24VDC for
inputting or with reversed polarity.
(Note 2) Ensure that the earth terminals LG and FG are grounded. (Ground resistance: 100 or less) Since the LG
terminals have potential of 1/2 input voltage, the operator may receive an electric shock when touching metal
parts.
(Note 3) When Q61P, Q63P, Q64PN or Q64P is loaded on the extension base unit, a system error cannot be detected
by the ERR terminal. (ERR terminal is always OFF.)
