Woodward 9905-971 LINKNET 16-Channel Discrete Input Module

Product Details:

The LINKnet distributed I/O network provides low cost, easy to implement distributed I/O capabilities for the NetCon control system.

The LINKnet I/O modules, while slower and less powerful than NetCon I/O modules,

are well suited for non-turbine control functions like sequencing and monitoring.

• Accuracy: 1 % at 25 °C without field calibration
• Power Supply Input: (18 to 32) V (dc)
• Isolation:

Network to I/O channel: 277 V (ac)

Power supply input to network: 277 V (ac)
I/O channel to I/O channel: 0 V (rms)
Power supply input to I/O channel: 500 V (dc) (except for discrete inputs; discrete input power comes directly from power supply input)

• Field Wiring: 2 mm² (14 AWG) maximum wire size
• Temperature Range: (–40 to +55) °C
• UL Listed: Class I, Division 2, Groups A, B, C, and D

ESD immunity: IEC 801-2 (1991) 8 kV air and 4 kV contact, HCP and VCP tests
Radiated RF immunity: IEC 801-3, 10 V/m +80 % 1 kHz AM, (80 to 1000) MHz
Fast transient immunity: IEC 801-4 (1988) 2 kV directly coupled onto power lines and 2kV capacitively coupled onto I/O network lines

• Scan Rate:

Less than 7 output modules:
(# of I/O modules x 6 + 75) ms typical
(# of I/O modules x 6 + 100) ms maximum
7 or more output modules:
(# of I/O modules x 6 + # of outputs)
