Product Information
- The BA368E is a two input, intrinsically safe panel mounting Counter that is compatible with a wide variety of sensors. It has IP66 front of panel protection and IP20 protection at the rear. The Counter is certified with IECEx, ATEX, and UKEX certificates, indicating that special conditions apply for safe use. It is important to note that an electrostatic charge can be generated, so the instrument enclosure should only be cleaned with a damp cloth.
- The Counter comes with terminals for optional 4/20mA output, as well as terminals for optional dual alarms. It also features pulse inputs, pulse outputs, and power supply connections. The display of the Counter shows the units of measurement, which are indicated by a printed scale card visible through a window on the right-hand side of the display.
- The scale card can be easily changed without removing the Counter from the panel or opening the instrument enclosure.
- In addition, the Counter requires specific wiring configurations for specified immunity and recommends using screened twisted pairs with screens earthed at one point within the safe area to ensure EMC compliance.
