Click! 511 Bid Specication

1.0 General. This item shall govern the purchase and installa-

tion of a digital I/O repeater module (DRM) equivalent to the

Wavetronix Click!™ 511. Test results and other documentation

demonstrating performance and capabilities shall be pro-

vided.

2.0 Product Description. The DRM shall be used to monitor

distributed digital outputs with serial devices, such as the

Wavetronix SmartSensor™. The DRM shall be used in either

server mode or client mode, where clients are used to send

information to the server. The DRM shall convert 2-wire half-

duplex RS-485 to half-duplex RS-232 and vice versa.

3.0 Physical. The DRM shall not exceed 0.29 lbs. (0.1 kg) in

weight.

The DRM shall not exceed 4.5 in. × 4 in. × 0.9 in. (11.4 cm x 10.2

cm x 2.3 cm) in its physical dimensions.

The DRM shall operate in the temperature range of -29°F to

165°F (-34°C to 74°C).

4.0 Mounting. The DRM shall mount to a DIN rail with hot-

swappable power and communication buses for quick installa-

tion and replacement.

5.0 Power. The DRM shall operate using less than 0.8 W of

average power at 10 VDC to 30 VDC.

6.0 Connections. The DRM shall include the following con-

nections for power and communication:

6.1 Power. The DRM shall include a 5-position connector,

with two contact points reserved for connecting power

through the bus.

The DRM shall supply voltage input monitoring with set-

table thresholds of 11.7 or 22.7 VDC.

6.2 Serial Ports. The DRM shall include the following

four independent physical serial ports:

7.0 Communication. The DRM shall have the following com-

munication capabilities:

7.1 Serial Protocol Conversion. The DRM shall allow

communications with any serial device that has a serial

connection by converting 3-wire half-duplex RS-485 com-

munication to half-duplex RS-232 communication, and

vice versa.

8.0 Baud Rate. The DRM shall operate at a baud rate of 9600

bps.

9.0 Conguration Features. The DRM shall have a push-but-

ton on the faceplate of the unit that:
