1. INTRODUCTION

1.1 PRODUCT OVERVIEW

The MFC Switchbox™ can be used to connect a molbox1™ MFC control option or an MFC-CB™ control

channel to up to five MFCs, or to one MFC and four MFMs. The rear panel of the MFC Switchbox

connects to the molbox1 or MFC-CB via a circular 5-pin connector and a 25-pin DSUB connector.

Cables are provided with the switchbox to facilitate these connections. A power cable is also provided.

The MFC Switchbox contains its own power supply which allows it to maintain continuous power on all

five devices under test (DUTs). The MFC Switchbox provides up to 55 watts of power. This allows it to

provide 260 mA per MFC when fully loaded. MFCs typically require a maximum of 200 mA. Therefore,

all five ports of the MFC Switchbox can be used simultaneously in most situations. Occasionally, when

calibrating older, power hungry MFCs, it may only be feasible to connect four MFCs at a time.

The front panel of the MFC Switchbox has five 25-pin DSUB connectors. These connectors are used to

connect the switchbox to the various DUTs.

Current controlled MFCs can only be used on channel 1. When testing MFMs, an MFC can be used for

controlling the flow in the test while taking the measurement data from the currently selected MFM.

This controlling MFC must be a voltage based MFC.

1.3 1.3 SUBASSEMBLY DESCRIPTION

1.3.1 POWER SUPPLY

Powers the electronics inside the MFC Switchbox and provides continuous power to up to

five connected DUTs. The switching power supply provides +5 volts at 0.5 amps and +15

volts at 4 amps. This 15 volt signal is converted via a DC-to-DC converter to -15 volts at 1.3

amps (leaving approximately 2 amps for the +15 volt signal). The enclosure is cooled by

active air circulation using a fan on the rear panel.

1.3.2 RELAY BOARD

Provides the control and signal switching required to connect (one at a time) up to five DUTs

to the molbox’s single MFC port.

1. INTRODUCTION

1.3.3 FRONT PANEL ASSEMBLY

Provides connecting ports for up to five DUTs.

1.3.4 REAR PANEL ASSEMBLY

Supports power, signal communication with molbox1 or MFC-CB, control communication with

molbox1 or MFC-CB and carries the cooling fan.

1.4 SPECIFICATIONS

1.4.1 GENERAL SPECIFICATIONS

Power Requirements 85 to 264 VAC, 50/60 Hz, 55 VA maximum consumption

Weight 1.5 kg (3.25 lb)

Dimensions 22.5 cm W x 7.5 cm H x 20.0 D (8.85 in. x 2.95 in. x 7.87 in.)

1.4.2 MFC CONTROL FUNCTION SPECIFICATIONS

The MFC Switchbox works with any MFC that can be used with the molbox1 or MFC-CB.

The switchbox provides the MFCs with continuous power, but the molbox1 or MFC-CB still

provides all the control and measurement. For detailed specifications regarding MFC control

please refer to specifications section of the molbox1 or MFC-CB Operation and Maintenance

Manual.

Current based MFCs can only be used when connected to device 1 of the MFC Switchbox.

It is not possible to switch between multiple current based MFCs.

The Valve Test Point signal is only available on device 1 of the MFC Switchbox.
