The following conventions are used to indicate and classify precautions in this manual. Always heed the information provided with them. Failure to heed precautions can result in injury to people or damage to property. !DANGER !WARNING Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. [. . . ] The actual node number setting range depends on the type of PLC in which the Master is mounted as well as the Master's settings. Refer to 2-1 Communications Specifications for details. Communications Mode Settings (SRT2 Series Only) The communications mode is set with pin 3, as shown below. Pin 3 OFF Communications mode Communications distance Communications baud rate 750 kbps Communications cycle time 0. 5 or 0. 8 ms High-speed Com- 100 m max. munications Mode Long-distance Communications Mode 500 m max. ON 93. 75 kbps 4. 0 or 6. 0 ms The communications mode settings using pin 3 only apply to the SRT2 Series and cannot be used with the SRT1 Series, which operate in High-speed Communications Mode at all times. 182 Remote Terminals Hold/Clear Outputs for Communications Error Section 5-1 Pin 4 is used to set the output data status when a communications error occurs, as shown in the following table.

CompoBus/S communications power supply Brown Brown CompoBus/S communications 2-wired sensor NPN output 3-wired sensor (photoelectric (limit switch) sensor or proximity sensor) Black Blue Blue Solenoid, valve Solenoid, valve The following diagram shows the terminal arrangement and wiring for the SRT@-MD16T-1. CompoBus/S communications power supply Brown Brown CompoBus/S communications 2-wired sensor PNP output 3-wired sensor (photoelectric (limit switch) sensor or proximity sensor) Black Blue Blue Solenoid, valve Solenoid, valve Note 1. The V terminals V1 and V2 are not connected internally, and neither are the G terminals G1 and G2 (I/O power supply). Care must be taken when connecting them. When inductive loads such as solenoids and valves are used, either use loads with built-in diodes that absorb the back-electromotive force or connect a diode externally. 184 Remote Terminals SRT@-MD16T/MD16T-1 Dimensions Section 5-1 The following diagram shows the dimensions for the SRT@-MD16T/MD16T-1. All dimensions are in mm. 180 (54) 50 58 (83) Mounting Holes 40±0. 2 Two, 4. 2 dia. or M4 170±0. 2 Note The circuit block can be removed by loosening the circuit block mounting screw. Before removing the circuit block for replacement, check that all power supplies, including I/O power supply, to the Unit are turned OFF. 5-1-6 SRT@-RO@ Remote Terminals with Relay/Power MOS FETs The following tables and graphs show the ratings and output specifications for the SRT@-RORatings Item Models SRT1-ROC08 SRT1-ROF08 SRT1-ROC16 SRT1-ROF16 SRT2-ROC08 SRT2-ROF08 SRT2-ROC16 SRT2-ROF16 SRT@-ROC08: 8 relay outputs SRT@-ROF08: 8 power MOS FET outputs SRT@-ROC16: 16 relay outputs SRT@-ROF16: 16 power MOS FET outputs (The 16-output Remote Terminals cannot be used with a CQM1-SRM21 Master Unit that is in 4-point mode. ) Specification Specifications Output points 185 Remote Terminals Item Communications mode Section 5-1 Specification SRT1-RO@: High-speed Communications Mode SRT2-RO@: High-speed Communications Mode or Long-distance Communications Mode Local power supply Power supply type Communications power 20. 4 to 26. 4 V DC (24 V DC +10%/­15%) supply voltage (including I/ (Power cannot be supplied from the communications O power supply) cable) Current consumption Noise immunity Common terminal current (COM 0, 1, and 2 through 7) Vibration resistance Shock resistance Dielectric strength Internal circuits: 350 mA max. at 24 V DC (Including relay coil current) ±1. 5 kVp-p with a pulse width of 0. 1 to 1 µs and a rise time of 1 ns (via impulse noise simulator) 3 A max. 10 to 55 Hz, 1. 0-mm double amplitude Malfunction: 100 m/s2 500 V AC (between insulated circuits) 2, 000 V AC (between all output terminals and the power supply or between all communications terminals and all different-polarity contacts) 20 M min. at 250 V DC (at the same locations as dielectric strength specs. ) Operating: 0 to 55°C (with no icing or condensation) Storage: ­20 to 65°C (with no icing or condensation) Operating: 35% to 85% (with no condensation) Storage: 25% to 85% (with no condensation) No corrosive gases M4 screws or 35-mm DIN track mounting 50 N Track direction: 10 N · m Pulling: 50 N Tightening: 0. 6 to 1. 18 N · m The node number is set on a DIP switch.
