GENERAL SPECIFICATIONS

Capacity: 4, 8 or 16 positions

Connection

DeviceNet: Euro type connector terminal (applicable

I/O: M3 screw terminals (torque 0.8 N·m)

Power input: M3 screw terminals (torque 0.8 N·m)

Screw terminal: Nickel-plated steel

Isolation: I/O to DeviceNet to power to FG1

Power indicator: Green LED turns on with power supplied.

DeviceNet COMMUNICATION

Transmission cable: Approved for DeviceNet

Node address setting: DIP switch; 00 – 63

Baud rate setting: DIP switch

125 kbps (factory default), 250 kbps, 500 kbps

MS (Module Status) indicator: Bi-color (green/red) LED

indicates device status.

NS (Network Status) indicator: Bi-color (green/red)

LED indicates status of the communication link.

INPUT SPECIFICATIONS

Input modules: Mini-M series; output 1 – 5 V DC;

(Each input must be isolated by signal conditioners. Non-

isolated modules such as M2BW is not usable.)

■ Analog Input

Input range: See each I/O module spec.

Voltage at the field I/O terminals limited within 30 V DC for

UL.

Isolation: transformer (by Mini-M module)

A/D conversion output: 16-bit binary

Signal range 0 – 100 % is converted into hexadecimal 0000

– 1770 (0 – 6000). -15 to 0 % is represented by 2’s

complements.

Overall range is represented by hexadecimal FC7C – 1AF4

(-900 – +6900), for -15 – +115 %.

Note: In the firmware version 3.00 or later, analog input

range 0 – 100% can be converted into hexadecimal 0000 –

2710 (0 – 10000).

In addition, negative values of analog input range -15 to 0%

can be converted into signed absolute values.

Refer to the instruction manual for details.

OUTPUT SPECIFICATIONS

Output modules: Model M2VS; input 1 – 5 V DC

■ Analog Output

Output range: See model M2VS spec.
