The SC250 is the hub of the secure logging system, for use with Eltek's Darca Secure software. It is not necessary to have a permanently connected PC and the built-in battery means data logging is not interrupted if there is a temporary AC supply failure. Alarms are included as standard (SMS and local) and include grouping so that alarms for individual departments can be configured.

Features

• Data Logger with integral receiver
• Alarms are logged
• Data is checksummed to prevent corrupted data from being downloaded
• 247K readings expandable to 2M readings
• Alarm raised if external power removed (e.g. mains failure)
• Grouping for alarm text messages
• Extensive communications options

SQ/RS485

RS232 to RS485 interface converter

This unit converts the standard RC250 or Squirrel RS232 interface to a RS485 interface; thereby allowing equipment with the RS485 interface to communicate with the receiver/logger.

• Allows much longer cable lengths than RS232 - RC250/Squirrel can be further away from the PC or other connected equipment
• All RC250 units (after serial number T-25194) are compatible with this device

If you require a new logger to work with this interface, please specify at the time of ordering. Existing loggers may need a firmware update to work with the RS485 interface - please contact Eltek for advice.

Squirrels using this interface must be mains powered.
