  • Frequency input. Easily user scaled.
  • For frequency measurements, the recommended meter is the BL-40F meter which has been designed specifically for that purpose.
  • Three frequency ranges of 99.99Hz, 999.9Hz and 9999Hz.
  • Optional isolated 16 bit analog output. User or factory scalable to 4 to 20 mA, 0 to 20 mA or 0 to 10 V across any desired digital span from ± one count to the full scale range of – 1999 to 9999 (12000 counts).
  • Auto-sensing AC/DC power supply. For voltages between 85- 265V AC / 95-370 V DC (PS1) or 15-48 V AC / 10-72 V DC (PS2).
  • Standard red or optional green or super bright red 4-digit LED
  • Three annunciator LEDs provide front panel alarm status indication for up to three setpoints.
  • Optional relays. One 10 Amp Form C and one 5 Amp Form A relay, or up to three 5 Amp Form A relays are available.
  • When analog output is installed, one 10 Amp Form C or two 5 Amp Form A relays can be supported.
  • There are 2 Plug-in Modular Input Signal Conditioners for this specialized frequency only member of the Leopard Family: IF05 & IF08


Texmate’s BL-40F series are economically priced frequency digital meter relays with isolated 4 to 20 mA retransmission or control loop output capability for measurement and control applications.
Ideal for OEM applications, more than 38 different Modular Input Signal Conditioners available for flexibility.

n.b. Special meter inputs can be factory scaled.
