Cooper Bussmann 915U-2 Wireless Mesh I/O and Gateway User Manual

Rev Version 1.2.2

The power supply should be CSA Certified Class 2, approved for normal operation. If the device is being used in a
Class I Div 2 explosive area, the supply must have Class I Div 2 approval.

When powering the module, the power source must be able to provide sufficient current to power all module
operations, including quiescent current, peak transmit current, and digital and analog I/O, including loop supply and
battery charging (if applicable). To calculate the power supply current limit, use the following criteria.

Current

@ 13.8V

@ 24V

Quiescent current of the module

200 mA

115 mA

Module maximum I/O (4xAI, 2xAO, 8xDO)

500 mA

290 mA

Peak transmit current

500 mA

290 mA

External expansion I/O

1000 mA

575 mA

Battery charging

N/A

575 mA

The following table shows t24V supply current limits with different module options enabled. Transmit current
is not added because it is not a constant.

Expansion I/O

No Expansion I/O

No battery fitted (no charging)

1270 mA

695 mA

Battery fitted

1555 mA

980 mA

The following table shows t13.8V supply current limits with different module options enabled. Transmit
current is not added because it is not a constant.

Expansion I/O

No Expansion I/O

Current limit

2200 mA

1200 mA

For example, if a module is powered by a 24 Vdc supply and there is no backup battery connected and it has
expansion I/O fitted, the minimum current needed is 1.3A @ 24V (32W). This is allowing for 290 mA peak transmit
current and up to 1A for the expansion I/O.

Expansion I/O Supply

To allow increased I/O capacity, a second four-way terminal labeled “Expansion I/O” provides a +12V supply
(up to 1A) and RS-485 communications for any 115S serial expansion I/O modules.
