Cryo-con Model 24C
Specifications, Features and Functions
Alarm Outputs
Alarm outputs include a LED indicator, an audible alarm, on-screen display and
remote reporting.
Alarms may be asserted based on high temperature, low temperature, input sensor
fault or heater fault conditions.
A user selectable dead-band is applied to all alarms.
The High and Low temperature alarms may be latched. See the Input Channel
Configuration Menu.

Note:
To clear a latched alarm, first press the Alarm key and
then press the Home key.
Relays
The Model 24C has two dry-contact mechanical relay outputs.
Relays are asserted or cleared based on the temperature reading of selected input
channels. Each output has a high and low set-point that may be enabled from the
front panel or a remote interface. Furthermore, relays can be manually asserted ON
or OFF.
Normally-Open contacts are available on the rear panel. Contact rating is 10A @125
VAC, 5A @250 VAC or 5A @30 VDC for resistive loads. Maximum switching power is
150W.
Remote Interfaces
Ethernet LAN and RS-232 interfaces are standard. IEEE-488.2 (GPIB) and USB are
external, field installable options. All functions and read-outs available from the
instrument may be completely controlled by any of these interfaces.
The LAN interface is electrically isolated and is 10/100-BaseT compliant. Connection
is made via the RJ-45 connector on the rear panel.
The Serial port is an RS-232 standard null modem with male DB9 connector. Rates
are 9600, 19,200 and 38,400 Baud.
When installed, the GPIB option is fully IEEE-488.2 compliant. Connection is made at
the rear panel's LAN port.
The programming language used by the Model 24C is identical for all interfaces and
is SCPI language compliant.
